9/14/22: Met with Garett, the owner, and asked for his opinion on a new HVAC system for 1901 sq ft single story house. I did not want a low-end model and asked his opinion about the high-end model. I also wanted one where the technology has been around a while and is very reliable. Garett said I would like the model between the low-end and high-end. I purchased the system he recommended. My old A/C was installed in 2003 by this same company and it served me well. Note: Garett said it is better to get a new HVAC system while the old one is still working. Meaning, you will be avoiding lots of undue stress caused when the old A/C goes out. 10/17/22 to 10/18/22: Andreas & Mark came out to install the new system. They were very friendly, informative, experienced installers. They paid attention to details and made sure everything was working properly before leaving. (I have an engineering mind and ask many questions) They disassembled the old furnace so it could be removed from the attic (the access to the attic was smaller than the old furnace). The new HVAC system works great. Went through a heat wave and through 45 degrees winter spells already. I am really impressed with the 2-stage system. It is very quiet and energy efficient. Don't even notice when it goes on. AC Pro Energy Star 3 ton 2 stage 16 SEER air conditioning with two stage veriable speed furnace and matching coil system. Furnace model: A80US2V070A12L-04 Air Conditioner model: 4SCU16LS136P-3 Indoor Coil model: PL36H145P44935 Comment: I saw signs of mold in the old Indoor Coil when it was removed and inquired how to prevent that from happening on the new system. Mark said there are a few systems that deals with mold. I then bought the one that their supervisor said was the better one: iWave-R Air Purifier. Mark installed it that same day. 11/18/22: At my request, Garett came out to hook up extra features that the Nest thermostat provides, it required more wires going to the thermostat then was provided by the old thermostat. Originally, I was to get a Honeywell thermostat, but they threw in a Nest 3rd gen thermostat. I've been with them 19 years: Thompson Plumbing - Heating - Air Conditioning 4749 Oceanside Blvd Ste J Oceanside, CA 92056

Navien will be sending a new check valve for the tankless unit. According to the Navien rep. He believes the check valve is stuck and allowing hot and cold water to mix and that’s what’s causing the water issue. Explained to customer that we will call him when the new part arrives so we can set up a day to come out and replace the part.

• Dishwasher has a high-loop drain line vs air gap. • Kitchen sink faucet hot/cold reversed. • Primary bathroom – west sink slow to drain. • Both toilets are not sealed at base to floor. - Inspect water heater and hot water issues Cleared sink in master bathroom by running a cable down the drain Lifted dishwasher drain hose as high as possible and secured it to the cabinet with a pipe strap. Master toilet was lose from the flange to toilet . Tighten down bolts and secured it properly. Added caulking to both toilets. Water heaters are located by the garages in front of the units. It appears the the building shares the water heaters. They’re is a recirculating pump at that water heaters but might not be working properly. That might be the reason why it takes a while for the unit to get the hot water. We recommend that the property manager have someone come out and test the pump or just replace it. ( Thompson plumbing can offer that service). The kitchen faucet is installed correctly.
